Ready for the GoPro Karma?

Emergency Shut Off?

A few times I've been in situations where it would have been helpful for Karma to shut off prior to officially landing. One of which was when Karma crashed and the propellors kept spinning until they all broke off and I was able to manually shut off on the body of the drone. Is there any emergency shut off I can do from the controller in the case of a crash or other similar situations?
